(Don't include 183 | the brackets!) The text should be enclosed in the appropriate 184 | comment syntax for the file format. We also recommend that a 185 | file or class name and description of purpose be included on the 186 | same "printed page" as the copyright notice for easier 187 | identification within third-party archives. 188 | 189 | Copyright [yyyy] [name of copyright owner] 190 | 191 | Licensed under the Apache License, Version 2.0 (the "License"); 192 | you may not use this file except in compliance with the License. 193 | You may obtain a copy of the License at 194 | 195 | http://www.apache.org/licenses/LICENSE-2.0 196 | 197 | Unless required by applicable law or agreed to in writing, software 198 | distributed under the License is distributed on an "AS IS" BASIS, 199 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 200 | See the License for the specific language governing permissions and 201 | limitations under the License. 202 | -------------------------------------------------------------------------------- /MAINTAINERS.md: -------------------------------------------------------------------------------- 1 | # Maintainers Guide 2 | 3 | This guide is intended for maintainers - anybody with commit access to one or 4 | more Code Pattern repositories. 5 | 6 | ## Methodology 7 | 8 | This repository does not have a traditional release management cycle, but 9 | should instead be maintained as a useful, working, and polished reference at 10 | all times. While all work can therefore be focused on the master branch, the 11 | quality of this branch should never be compromised. 12 | 13 | The remainder of this document details how to merge pull requests to the 14 | repositories. 15 | 16 | ## Merge approval 17 | 18 | The project maintainers use LGTM (Looks Good To Me) in comments on the pull 19 | request to indicate acceptance prior to merging. A change requires LGTMs from 20 | two project maintainers. If the code is written by a maintainer, the change 21 | only requires one additional LGTM. 22 | 23 | ## Reviewing Pull Requests 24 | 25 | We recommend reviewing pull requests directly within GitHub. This allows a 26 | public commentary on changes, providing transparency for all users. When 27 | providing feedback be civil, courteous, and kind. Disagreement is fine, so long 28 | as the discourse is carried out politely. If we see a record of uncivil or 29 | abusive comments, we will revoke your commit privileges and invite you to leave 30 | the project. 31 | 32 | During your review, consider the following points: 33 | 34 | ### Does the change have positive impact? 35 | 36 | Some proposed changes may not represent a positive impact to the project. Ask 37 | whether or not the change will make understanding the code easier, or if it 38 | could simply be a personal preference on the part of the author (see 39 | [bikeshedding](https://en.wiktionary.org/wiki/bikeshedding)). 40 | 41 | Pull requests that do not have a clear positive impact should be closed without 42 | merging. 43 | 44 | ### Do the changes make sense? 45 | 46 | If you do not understand what the changes are or what they accomplish, ask the 47 | author for clarification. Ask the author to add comments and/or clarify test 48 | case names to make the intentions clear. 49 | 50 | At times, such clarification will reveal that the author may not be using the 51 | code correctly, or is unaware of features that accommodate their needs. If you 52 | feel this is the case, work up a code sample that would address the pull 53 | request for them, and feel free to close the pull request once they confirm. 54 | 55 | ### Does the change introduce a new feature? 56 | 57 | For any given pull request, ask yourself "is this a new feature?" If so, does 58 | the pull request (or associated issue) contain narrative indicating the need 59 | for the feature? If not, ask them to provide that information. 60 | 61 | Are new unit tests in place that test all new behaviors introduced? If not, do 62 | not merge the feature until they are! Is documentation in place for the new 63 | feature? (See the documentation guidelines). If not do not merge the feature 64 | until it is! Is the feature necessary for general use cases? Try and keep the 65 | scope of any given component narrow. If a proposed feature does not fit that 66 | scope, recommend to the user that they maintain the feature on their own, and 67 | close the request. You may also recommend that they see if the feature gains 68 | traction among other users, and suggest they re-submit when they can show such 69 | support. 70 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # WARNING: This repository is no longer maintained :warning: 2 | 3 | > This repository will not be updated. The repository will be kept available in read-only mode. 4 | 5 | [![](https://img.shields.io/badge/IBM%20Cloud-powered-blue.svg)](https://cloud.ibm.com) 6 | [![Platform](https://img.shields.io/badge/platform-java-lightgrey.svg?style=flat)](https://www.ibm.com/developerworks/learn/java/) 7 | 8 | # Create and deploy a Java Backend For Frontend (BFF) using Java EE 9 | 10 | > We have similar patterns available for [Node.js](https://github.com/IBM/nodejs-backend-for-frontend), [Swift](https://github.com/IBM/swift-backend-for-frontend), and [Java Spring](https://github.com/IBM/spring-backend-for-frontend) as well! 11 | 12 | In this code pattern, you will create a Backend for Frontend (BFF) web service using Java EE [MicroProfile](https://microprofile.io/) running on [WebSphere Liberty](https://developer.ibm.com/wasdev/), matching a RESTful API documented in [Swagger](https://swagger.io/). 13 | 14 | A BFF can be used to elegantly expose complex backend systems to multiple client-facing platforms, such as iOS and the web, without building a monolothic API that attempts to serve all clients equally. Different types of clients require different types of user experiences, and having a backend API tightly coupled to each specific user experience actually makes for a much more loosely coupled system overall. This pattern helps frontend teams iterate on features faster by giving them more control over the APIs they interact with, without affecting the user experience or development team driving a sister frontend. 15 | 16 | When you have completed this code pattern, you will understand how to: 17 | 18 | * Build out the Backend for Frontend (BFF) architecture pattern 19 | * Deploy to Kubernetes, Cloud Foundry or a DevOps Pipeline 20 | * Operate an application with monitoring and distributed trace 21 | * Connect to provisioned services 22 | 23 | ![](doc/source/images/architecture.png) 24 | 25 | ## Video 26 | 27 | Learn more about the Backend for Frontend pattern in this tech talk: 28 | 29 | [![BFFs and GraphQL, terms you should know and why](https://img.youtube.com/vi/B5OdK21ZevI/maxresdefault.jpg)](https://www.youtube.com/watch?v=B5OdK21ZevI) 30 | 31 | ## Steps 32 | 33 | > As an alternative to the steps below, you can [create this project as a starter kit](https://cloud.ibm.com/developer/appservice/create-app?starterKit=704af9af-c07b-33ab-881c-e89ec39b0aae) on IBM Cloud, which automatically provisions required services, and injects service credentials into a custom fork of this pattern. Then, you can skip directly to step 4 below. 34 | 35 | 1. [Install development tools](#1-install-development-tools) 36 | 1. [Configuration](#2-configuration) 37 | 1. [Project contents](#3-project-contents) 38 | 1. [Run](#4-run) 39 | 40 | ## 1. Install development tools 41 | 42 | * [Maven](https://maven.apache.org/install.html) 43 | * Java 8: Any compliant JVM should work. 44 | * [Java 8 JDK from Oracle](https://www.oracle.com/technetwork/java/javase/downloads/index.html) 45 | * [Java 8 JDK from IBM (AIX, Linux, z/OS, IBM i)](https://www.ibm.com/developerworks/java/jdk/), 46 | or [Download a Liberty server package](https://developer.ibm.com/wasdev/downloads/download-latest-stable-websphere-liberty-runtime/) 47 | that contains the IBM JDK (Windows, Linux) 48 | 49 | ## 2. Configuration 50 | 51 | The application is configured to provide JAX-RS REST capabilities, JNDI, JSON parsing and Contexts and Dependency Injection (CDI). 52 | 53 | These capabilities are provided through dependencies in the `pom.xml` file and Liberty features enabled in the server config file found in `src/main/liberty/config/server.xml`. 54 | 55 | ## 3. Project contents 56 | 57 | The BFF application has a health endpoint which is accessible at `:/javalibertybackendforfrontend/health`. The context root is set in the `src/main/webapp/WEB-INF/ibm-web-ext.xml` file. The ports are set in the `pom.xml` file and exposed to the CLI in the `cli-config.yml` file. 58 | 59 | The project contains IBM Cloud specific files that are used to deploy the application as part of a IBM Cloud DevOps flow. The `.bluemix` directory contains files used to define the IBM Cloud toolchain and pipeline for your application. The `manifest.yml` file specifies the name of your application in IBM Cloud, the timeout value during deployment and which services to bind to. 60 | 61 | Credentials are either taken from the `VCAP_SERVICES` environment variable that IBM Cloud provides or from environment variables passed in by JNDI (see the server config file `src/main/liberty/config/server.xml`). 62 | 63 | ## 4. Run 64 | 65 | To build and run the application: 66 | 67 | 1. `mvn install` 68 | 1. `mvn liberty:run-server` 69 | 70 | To run the application in Docker use the Docker file called `Dockerfile`. If you do not want to install Maven locally you can use `Dockerfile-tools` to build a container with Maven installed. 71 | 72 | The application exposes the following endpoints: 73 | 74 | * Health endpoint: `://health` 75 | * Swagger API: `:/ibm/api/explorer/`, you will need to login with the credentials set in your `server.xml` file. By default these are `guest` and `password`. 76 | 77 | The context root is set in the `src/main/webapp/WEB-INF/ibm-web-ext.xml` file. The ports are set in the `pom.xml` file and exposed to the CLI in the `cli-config.yml` file. 78 | 79 | ## License 80 | 81 | This code pattern is licensed under the Apache License, Version 2.
